The Office 365 Network actually replaces the Office 365 technical forums that were based on Yammer signups. Microsoft isn't discontinuing Yammer, the company's enterprise social networking service, but Yammer won't be the basis of the new Office 365 Network. The earlier Yammer-based forums had typically keyed off so-called "YamJams," a sprawling series of Q&A sessions that Microsoft hosted from time to time. Brand Video Ads allows the target audience to get a complete visual tour of the brand’s product and it’s features. However, you had to be a part of a particular Yammer Office 365 group to know that these YamJams were taking place.
